Facebook share image problem

Hi everyone,
I run a site called https://www.theinspiration.com.
a few days ago my facebook share button stopped working. I can still share, but I dont get any fb meta data with, when sharing it.

When i try to linter it:

I get: Critical Errors That Must Be Fixed
Error Scraping Page: Bad Response Code

If i just copy the source code, and make a plain HTML file, post it on a server and linter it, it works with all meta data. (really I just need to have the fB thumbnail image working, when sharing)

I run W3 Total Cache and CDN (amazon) and I read that this might be why, but when i disable W3 Total Cache, I still get the error.

I spend 10 hours trying to figure it out today. Can someone help me?

Thanks.
Daniel
